All figures and tables, along with any supplementary material and additional information, are available at https://lhcbproject.web.cern.ch/lhcbproject/Publications/LHCbProjectPublic/LHCb-PAPER-2017-030.html. Updated version corrects a typographical error in two of the systematic uncertainties and corrects the corresponding tables
